Here's that Interlude I promised. It's short but ties up some loose ends from Daughters of Time.

Though they weren't exactly a traditional family, and none of them celebrated American holidays, Josie had gotten it set in her mind that they should have Thanksgiving dinner together in November. She had even convinced the Doctor an Professor to come. Her grandfather and Billie's Aunt Sarah and cousin Luke came as well, all looking completely amused at the girl's hyperactivity.

Josie wasn't actually that great of a cook however (she was known to burn water on several occasions) so all of the cooking being done in the Hub's tiny kitchen was Billie's territory, with the help of Sarah Jane and Gwen. Ianto turned out to be a lot of help as well. Turns out he can do more than brew a fantastic cup of coffee.

Jack had been all smiles in the morning as he began setting up the various plastic folding tables for everyone to fit. Josie had been teasing him, feet kicked up on his desk as she watched, refusing to do anything as she had been the one to convince them all to do this in the first place and that was clearly enough work for an army. Jack's laugh cut short when Billie emerged from the TARDIS (it was parked in the corner of the Hub where it wouldn't get in the way) with the Professor, carrying bags of groceries. She was wearing her deceased brother's AC/DC sweater and her hair was pulled back in a ponytail. The converse the Doctor had given her for her birthday weren't tied, the laces tripping her every couple steps, much to the amusement of the Professor. Jack's smile had turned soft at the sight but his eyes were wide with shock and understanding.

"Sparrow? What's wrong?" Josie nudged him slightly with her bare foot where he had leaned against the desk with a sigh.

"Nothing. Everything's perfect, Josie. Don't worry." His eyes trailed over his team and family buzzing around busily. "I just have something I need to do before tonight."

"Okay," Josie drawled out, dropping her feet to the ground and bouncing up out of the seat. "Well I'm going to see if anyone needs help." She pressed a kiss to Jack's cheek as she passed him. Whatever had come over him was clearly none of her business and she was in too good a mood to pry. Maybe after dinner.

Jack managed to corner the Professor a little while later in the kitchen. The alien was sitting at the tiny breakfast table in the corner, watching the women and Ianto flit about the kitchen in synchronized movements. If he didn't know better, he'd say those four had been doing this every year together for most of their lives, instead of them only having met a few weeks ago (Sarah Jane a few hours ago).

The human sank down in the chair across from the Time Lord, "Professor."

The alien turned his attention reluctantly from the brunette in front of him.

"Do you happen to remember that conversation we had when I first came on the ship after meeting Billie and Josie?"

The Professor blinked twice as understanding flooded his features, "Now?"

Jack looked back over to his sister, seeing her exactly as he remembered first meeting her, even with the fond look in her eyes anytime her gaze landed on him. She gave him a grin when she caught him staring and stuck her tongue out, probably thinking he was going to tease her for her cooking abilities. Domestic still wasn't a word that went down well in the TARDIS, even if it was one of the most homey feeling places Jack had ever stepped foot in. He constantly was calling Billie and the Professor "mom" and "dad" since they got together.

"Now," he agreed when Billie was distracted by her aunt once again.

The Professor nodded and stood, easily slipping an arm around Billie's waist and drawing her away from the kitchen while explaining about circular paradoxes in a whisper. Jack stood to watch them enter the TARDIS, Billie looking up briefly to shoot him a small reassuring smile. She'd keep their timelines intact. She didn't want their relationship to change any more than he did.
